Description

...when i run t2t-decoder, an error occur, why and what happen? here is the command: t2t-decoder --data_dir=data --problem=translate_enzh_wmt32k --model=transformer --hparams_set=transformer_base_single_gpu --output_dir=train --decode_hparams="beam_size=4,alpha=0.6" --decode_from_file=test10.10 --decode_to_file=translation_test.en

and the error: INFO:tensorflow:Inference results OUTPUT: 翻版 INFO:tensorflow:Inference results INPUT: C INFO:tensorflow:Inference results OUTPUT: C INFO:tensorflow:Inference results INPUT: B INFO:tensorflow:Inference results OUTPUT: B INFO:tensorflow:Inference results INPUT: A INFO:tensorflow:Inference results OUTPUT: A INFO:tensorflow:Elapsed Time: 5906.26919 INFO:tensorflow:Averaged Single Token Generation Time: 0.0030321 INFO:tensorflow:Writing decodes into translation_test.en INFO:tensorflow:Running decode hooks.

anyone tell me why? thanks very much!

I met the same problem, too

Same problem with t2t-decoder; however, the translation file can be produced eventually.

One more finding, when using --checkpoint_path rather than --output_dir, there will be no error.

Yes, I tried this approach, it works...

More specific, change --output_dir=model-dir to --checkpoint_path=model-dir/model-name, model-name without extension name (eg. --checkpoint_path=./basemodule/model.ckpt-180000. Hope my exp. can help more people:smile:
